“Any design based on a written spec is a design based on theory. A design based on a prototype is a design based on experience and practice… Prototyping has given us the power to show and tell the story of our design solutions to any given problem rather than just tell the story waving our hands in the air to describe the magic.” – Todd Zaki Warfel

“Ease of use isn’t the only measure of a positive user experience; pleasurably is just as important. Something can be dead simple, but if it’s outrageously boring or cold it can feel harder to get through. Designs should have flourishes of warmth, kindness, whimsy, richness, seduction, wit — anything that incites passion and makes the person feel engaged and energized.” – Whitney Hess

“More important than knowing all about the people we design for, we should have a deep understanding of the specific activity we’re supporting with our design… The most important question we can ask is not ‘who is using your software?’ but ‘what are people using your software doing?’.” – Designing for the Social Web by Joshua Porter
